Imagine having peace of mind when the power goes out, knowing that your refrigerator will continue humming, your lights will stay on, and you'll keep connected to your world. Many of us are beginning to consider home battery backup systems, oftentimes paired with solar panels, not only as a solution for power outages but also as a step towards greater energy independence and financial savings.
Whether you're looking to harness solar energy, tap into overnight tariffs, or simply equip yourself against power cuts, it's essential to have a sound understanding of several factors that guide this investment.
Let's break down the various components of the system you need to evaluate when considering solar power and battery backup for your home. From understanding your energy usage, determining backup needs to exploring solar panel and battery options let us guide you on the whole journey.
Understanding Your Energy Usage: How to Calculate Your Average Daily Electricity Consumption
To navigate your way through the often complex world of solar power and battery-backup setup, you need to understand your energy needs first. Looking at your utility bills or employing a smart metre can help uncover what your daily or monthly electricity consumption is. Remember, this value, known in the energy industry as kilowatt-hours (kWh), forms the bedrock of your solar power planning. It's your compass, guiding how much energy you need your solar panels to generate and the battery capacity required to store it.
Backing up Your Energy: Exploring Your Needs
Power outages can be disruptive, but planning can mitigate much of this disruption. It's essential to identify which appliances or devices in your home you absolutely need to function during these outages. This could be anything - from essentials like lights and your refrigerator, to your TV or heating system. If you aim for full home backup, this would, of course, increase the battery size needed - so it's a crucial factor to contemplate.
The Power of the Sun: Investing in Solar Panels
Solar panels - the heroes of any solar power system - work by converting sunlight into power. Factors such as the space available on your roof, the amount of sunlight your location gets, and your budget, all come into play when you're considering how many solar panels you'll need. These panels generate the energy that either gets used directly, stored in your battery for later, or sometimes even sold back to the grid.
When it comes to accommodating solar panels, you'll want to consider your location's daily sunlight hours and balance this against your budget for panels. Naturally, the more solar panels you install, the higher your potential energy yield. However, keep in mind that installing a massive array does not automatically translate to an overabundance of power. An important aspect to think about is your solar panel's efficiency, which refers to their ability to convert sunlight into electricity. This varies from panel to panel, but generally, they fall within the range of 15-20%.
Another vital factor to put into consideration is the position and angle of your panels, which affect how much sunlight they'll receive. Being in the Northern Hemisphere, south-facing roofs are often considered the best for solar panel installation. Also, you'll need to consider any obstructions, like taller buildings or trees, that could block the sun's rays. Hence, it becomes crucial to think through placement and overall system design to optimise production.
Unravelling Inverters: Transforming Solar Power into Usable Energy
Ever wondered how the energy absorbed from the sun by your solar panels becomes usable in your household? The secret is in the inverter.
An inverter is like a translator for energy. It takes the Direct Current (DC) electricity that your solar panels generate and converts it into Alternating Current (AC) electricity. AC is the standard used by most household appliances and gadgets, so having an efficient inverter is key to making the most out of your solar panels.
Additionally, when choosing an inverter, you also need to consider its capacity. This should be in line with the total output of your solar panels and the energy requirements of your home. Buying an inverter with too low a capacity could underutilise your solar power system’s potential, while one with an excess capacity may bring unnecessary product and installation costs.
Some inverters also come with advanced features, such as enhanced peak power and overload capacity. These can deal with short-term highs in energy demand, like when an appliance starts up. Others feature remote control and monitoring capabilities so you can keep track of your energy usage and solar system performance in real-time.
Selecting a battery that works seamlessly with your Inverter will ensure a smooth installation - that's why all of our pre-assembled Fogstar Energy batteries contain pre-loaded protocols for all major inverter brands (Sunsynk, Solis, Victron, Sofar, Growatt). It only takes a few seconds to change your protocol using the LCD screen, absolutely no complex BMS software is needed.
Capacity Matters: How Long Does Your Battery Last?
Battery capacity is a vital factor in your energy backup plan. Measured in kWh, your battery's capacity determines how long you can keep the lights on during an outage. Greater capacity translates into longer-lasting backup power.
When scoping your install, keep in mind that the average UK semi-detached home can use anywhere between 8-10kWh of energy a day. Starting gradually and expanding your capacity gradually might be a suitable strategy for you. Opting for the proper inverter and battery system from the onset facilitates this growth. For instance, embracing Fogstar Energy batteries permits you to securely connect up to 15 units simultaneously!
Installation: The DIY Approach Versus Pre-Assembled Batteries
While some solar and battery backup systems are relatively DIY-friendly, others require a meticulous setup process, and possibly expert hands. How you approach your choice of battery all comes down to your system, your DIY skills and how much time you have to spend on your system.
Our pre-assembled Fogstar Energy batteries have been created to be 'plug-and-play', meaning you can have your new battery up and running within 20 minutes. They are perfect for DIY installs or great solutions for your MSC approved installer.
If you're dedicated to building your very own solar battery, there are a couple of options. Some like to use a selection of EVE Cells to construct a 48V battery, others prefer to use kits, such as the Seplos Mason ones.
In the end, whether you're going the DIY route or using a pre-assembled system, the goal remains the same; attaining self-sufficiency, saving on energy bills, and contributing to a cleaner planet.
Choosing Your Power Reserve: Lithium Batteries
Lithium batteries (LiFePO4) have become a popular choice among homeowners because of their safety, efficiency and long lifespan. They provide an excellent reserve of power for your home, adding another layer of security and comfort to your energy supply.
Today, the technology behind these batteries is evolving rapidly, improving their performance and charging processes, not to mention prices of lithium have fallen dramatically. They certainly represent the future of home energy storage.
Counting the Cost and Benefits: Solar Power as an Investment
While investing in a solar battery system requires an initial expenditure, it's crucial to see beyond the upfront costs and consider the potential savings. Over time, your reliance on the national grid diminishes, cutting down your utility bills. In fact, with solar battery storage, it's entirely possible to become energy self-sufficient, relying on the sun for all your power needs.
Long-term, solar power is not only a good investment for your wallet but also for the environment. Solar energy is a clean, renewable source that doesn't produce greenhouse gases that harm our climate. Thus, going solar aligns with global efforts towards sustainable living and reducing our carbon footprint.
Conclusion
In conclusion, investing in solar and battery backup systems for your home offers both financial and environmental returns. By understanding your average daily electricity consumption and back-up power needs, you can better tailor your system. Choosing the right combination of solar panels, battery capacity, and technology, including an efficient inverter and durable lithium batteries, maximises your solar power yield. Not only will you enjoy peace of mind during power outages, but you will also contribute towards a sustainable future. It's a small step to reducing greenhouse gas emissions and leaves a safer world for future generations - a life powered by the sun is a brighter one for all.
